Application filed July 17.1907. Serial No. 384,158.

To all whom it may concern:

Be it known that I, JOHN HUDSON, a citizen of the United States,residing at Hamlin, in the county-of Jones, State of Texas, haveinvented certain new and i useful Improvements in Cotton-Choppers; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will' enable others skilled in theart to which it appertains to make and use the same.

This invention relates to new and useful improvements in cottonchoppers, and it has more particular reference to a cotton chopper oithat type which includes an oscillating lever carrying a chopping hoeand which is driven by suitable gearing from the traction wheels of themachine.

The invention aims as a primary object to provide novel means forpermitting of the adjustment of said hoe to selected positions.

The invention aims as afurther object to provide a novel construction,combination and arrangement of parts, the details of which will appearin the course of the following description in which reference is had tothe accompanying drawings forming a part ofthis speciication, likecharacters of reference designating similar parts, throughout theseveral views, wherein:

Figiue l is a top plan view of a machine constructed in accordance withthe present invention. Fig. 2 is a side elevation thereof. Fig. 3 is afront elevation thereof. Fig. 4 is a rear end elevation thereof. Fig. 5is a detailed view oi a slotted standard comprehended in the invention.Figs. 6 and 7 are detailed end and side elevations of a sliding baseembodied in the invention. Fig. 8 is a side elevation of one of thelevers embodied in the invention, showing a slot provided in the bodythereof.

In the accompanying drawings, the numeral l designates an open framesubstantially rectangular which at its iront end, supports a tongue 2and at its rear end supports a block 3, the spring post 4 havingconnection with the latter by means of bolts 5, the post 4 carrying thedrivers seat 6. At the rear end of the frame a U-shaped casting 7 issupported between the side bars thereof and the post 4 is extendedangularly beneath this casting connected therewith The depending legs 8of the casting 7 are formed to surround the axle 9 and are braced withrelation to the frame by diagonal straps l0. The axle 9 carries thetraction wheels ll. At one side of said axle, a wheel l2 is splined, thelatter being formed with crown teeth 13 and being forced inwardly by anexpansive coil spring 14 bearing against the said wheel and against thecollar l5 provided on the axle 9. The wheel l2 is formed with aninwardly extending hub 16 about which is engaged a yoke I7, the arm ofthe latter having suitable connection with a foot lever 18 working abouta quadrant 19, the lever I8 being employed to force the wheel l2outwardly against the tension of the spring 14. I

At the opposite side of the frame to the wheel l2, a longitudinal bar 20is provided with which is connected a laterally projecting member 2l ofsubstantial U shape, the parallel portions 22 of which are projectedthrough eyes 23, depending-from a laterally slidable plate 24 as guides.The plate 24 is provided at each side thereof, with alined bearings 25in which is journaled a shaft 26, the latter at its rear end havingconnection by means of a gimbal joint 27 with an inclined shaft 28, thelatter being preferably made in detachably engaged sections and carryingat its rear end a pinion 29 which meshes with the teeth I3 of the wheell2, the shaft 28 being journaled in a bearing 30 projected laterallyfrom the frame I. The shaft 26 carries at its front end a crank arm 3lfrom which projects a wrist pin 32.` Surrounding the latter is thesleeve 33 carried by a pitnian 34. Pivotally mounted in a slot 20, atthe lront end of the bar 20, is a post 35 which is constructed `withcommunicating slots 36 and 37 on relatively opposite sides thereof.Fixed to the lower end oi the post 35 is a supporting member 38, andpivoted to the upper end of the latter is a lever 39, the latter beingprojected through the opposite registering slots 36. The lever 39 isformed between the slots 36 with a longitudinal slot 40, and the pitman34 is projected through the latter and through the slots 37 in theirregistering relation. The end of the pitman 34 is engaged in a socket 4lprovided upon the end of the shank 42, the latter carrying a hoe 43.

The supporting member 38 has pivotal connection between its ends with alink 44 and the latter is in turn pivoted to a lever 45, which at itslower end is pivoted to the bar 20.

Mounted upon the plate 24, is a bracket 46 having a reduced upper end 47which projects through a longitudinal slot 48 provided in a lever 49,the latter at its front end being pivoted as at 50 to a bracket 5l,supported from the trame l.

In use, therefore, assuming that the wheel l2 is in mesh with the pinion29 and the machine is being advanced over the field, the shaft 26 willbe rotated through the means described and such rotation will result inoscillating the pitman 34, the pivot oi the latter being located at thepoint where it passes through the slot 40 of the lever 39. It will beapparent therefore, that the direction and amplitude of oscillation ofthe pitman 34 will be varied in accordance with the adjustment ot' thelever 39. When the lever 39 is raised or lowered, the pitman 34 is ofcourse correspondingl y moved on the wrist pin 32 as a pivot, and bymeans oi such movement, the hoeI is set to work at a' greater or lessdistance from the ground as desired. Should it be desired to cause thehoe to lmiss a hill of cotton in its stroke, the lever 45 is thrownforwardly. Should the row that is being chopped extend in a crooked linethe lever 49 is rocked on its pivot 50 and in such action slides theplate 24, the portions 22 serving as guides for said plate in thissliding movement, whereby the hoe is caused to follow the course of therow.

It will of course be understood that the several levers herein speciedwork about the conventional rack quadrant shown and are provided withtrigger operated pawls for engagement with said rack quadrant to holdsaid levers at selected positions.

The invention is simple in its structural details, inexpensive tomanufacture and practical and eicient in use.

From the foregoing description it will be seen that simple and efficientmeans are provided for accomplishing the objects oi' the invention, butwhile the elements herein shown and described are well adapted to servethe functions set forth, it is obvious that various minor changes may bemade in the proportions, shape and arrangement of the several parts,without departing from the spirit and scope of the invention as definedin the appended claims.

What is claimed is:

1. A machine of the type set forth, comprising a frame, a shaftsupported thereby, traction wheels carried upon said shaft, a postcarried by the frame and formed with communicating slots in all thefaces thereof, a slidably adjustable plate, a shaft mounted on saidplate, gearing between one of said traction Wheels and said shaft fordriving the latter from the former, a crank arm carried by said shaft, aptman pivoted to said crank arm, a lever pivoted adjacent said post andprojected through-a pair of opposed slots, said lever' being formed witha slot between the slots of said post, said pitman being projectedthrough said last named slot, a shank secured to the end of said pitman,a hoe carried by said shank, and means for adjusting said platelaterally with relation to said frame.

2. A machine of the type set forth, comprising a frame, a shaftsupported thereby, traction wheels carried upon said shaft, a pivotallymounted post carried by the frame and formed with communicating slots inall the faces thereof, a slidably adjustable plate, a shaft mounted onsaidplate, gearing between one of said traction wheels and said shaftfor driving the latter from the former, a crank arm carried by saidshaft, a pitman pivoted tosaid crank arm, a member secured to said post,a lever pivoted to said member and projecting through a pair ofregistering slots in said post, said pitman beingl projected throughsaid last named slot, a shank secured to the end of said pitman, a hoecarried by said shank, means for adjusting,l said plate laterally withrelation to said frame, and means for adjusting said post on its pivot.

ln testimony whereof, I alix my signature, in presence of two witnesses.

JOHN HUDSON.
